.'SPECIFICATIONforming part of Letters Patent No. 346,059, dated July 20,1836.

Application tiled October l2, 1885. Serial No. 179.708, (No model.)

To all whom, it may concern:

Be it known that we, JUNIUS AUGUSTUS MURPHY and Mancus TULLrUs MURPHY, citizens of the UnitedStates, residing at New Orleans, parish of Orleans, State of Louisiana, have invented new and useful Improvements in Oil-Cake Mats, of which the following is a vfull and exact description, reference being had to the accompanying drawings, making part of this specification.

This invention relates to that class of oilpress mats the body or leaves of which are composed of woven material, and the nature thereof consists in the combination of hair warps and combined hair and wire woofs, the former compressed together and the latter adapted to hold the former in its compressed state, preventing any expansion of same, either while lying in stock or when subjected to the action ofthe press.

In the accompanying drawings, Figure l is a plan or top view of our mat body or leaves, a portion of which is shown as finished and the balance only partially so. Fig. 2 is a perspective view of the mat complete.

On the drawings, the letter a designates a series of bars, which are arranged at uniform distances apart across a suitable frame to permit of the weaving of the warp b between same. This is done by drawing the said warp from one end of the frame over the first bar, thence under the second and over the third bars, and in continuing the said process until the last bar is reached, when the warp is drawn tightly around same and returned alternately under and over the different bars to the startingpoint, from whence it is in like manner carried back and forth until a sufiicient quantity of warp to produce a given size mat has been woven on the rods. A pair of clamping-bars (not shown in the drawings for the reason that they form no part of the invention proper) are then placed on the ends of the bars a at each side of the woven material, and with the said material and bars are next removed to a hyin which the said plates are until the material draulic press, pressed toward each other between same has been reduced to the requisite width of mat required, when the plates are secured together by the aid of suitable fastenings and the material removed from the press. One of the rodsa is next withdrawn from the woven material, and a woef-rope, composed of strands of hair, hemp, or other suitable material, c, and wires c', is snugged into the hole left thereby. In like manner. the different rods a are successively withdrawn and replaced by the w'oof-rope,which is tightly drawn through the same, and' thus by its alternating course is made to securely bind the warp in'its compressed state and to impart a finished or selvage edge to each side of the mat. The mat thus formed is adapted to be folded at its center, so as to be opened or closed as occasion may require, and the back of the mat is covered with leather, f, having a handie, l1., secured to the hinge or folding part thereof to facilitate the handling of same. An edging or round rope, t, is sewed into each edge of the mat, as in other mats used for a similar purpose.

Te are aware that oilApress mats have been heretofore used in which wire has been woven with the ropes, as shown and described in Letters Patent No. 150,91 to XV. Il. Crocker, but in this case the center or middle ribs forming the hinge are made of hair rope without wire. XVe are also aware of patent to T. H. Murphy, No. 170,586, in which the wire is woven with the warp-ropes, but without crossing the center of the mat. In the first case a different woef is used in the center or hinge of the mat, and in the other case the wire is woven in the leaves only. In our construction the combined hair and wire woof is woven from side to side of the mat throughout its whole length, which prevents any expansion in its width, while in no manner interfering with the fold ing of its hinge or center.

Heretofore in the construction of woven mats we have pressed so many warps into a given space that the usual hair woof would not hold them without expanding; consequently we had for a time to decrease the number of warps and produce an inferior article to expanding in width and adapted to be folded that which we now manufacture as above dein the center, as set forth.

In testimony whereof we affix our signatures Vhat we claim as new, and desire to secure in presence of two witnesses. 5 by Letters Patent, is- Y An oil-press mat having its warp-ropes comy posed of hair and its Woof-ropes of combined w hair and wire, the Woof-ropes woven through Vitnesses: the mat from end to end, substantially as de- ANDREW HERO, J r., 1o scribed, whereby the mat is prevented from HENRY GOVAN.
